This is true but I just mean in terms of his power at 160. Benavidez and Morrell are a lot naturally bigger than him
He gets beat a lot. Eubank beat him and Eubank wasn't very big. Definitely that generation before would beat him up, Froch, Groves, Kessler would KO him badly. Ward would hug him badly, maybe even KO him with the size difference.
Eubank might not have been tall compared to todays 6 feet plus super middles but he was big at the weight, he notoriously struggled to make weight at 168 and did campaign at 175 and even 190 with some modicum of success. Agree Benn would of struggled in that Super 6 era. Froch/Benn would of been fight of the year material but I could see Froch outlasting Benn. Kessler likely beats him too, Ward definitely beats him. I don't think Groves beats him though, Groves often found a way to lose and probably gets KO'ed by Benn.
Eubank was far bigger than Benn and they drew in their rematch, Eubank went the distance with Thompson who wa a cruiser that knocked David Haye out.
